I flashed the old WiFi drivers and to be honest, it works better than ETaNa Feb 03 and previous versions (using ETaNa 04 Feb with old Wifi drivers).

Also, I haven't seen any BSODs anymore. Using SetCPU with different profiles and your default voltages.

I just set the lower frecuency to 456 and it works great.
[LG Optimus 2x] Schmeichel1:
For me old drivers works better too with new some connection problems.

+1 : same for me

2G : about 2/3mA in idle...

3G : close to 45mA in idle too

is there any baseband/kernel/rom combination (may be an updated driver/module?) I took a look and changed some build.prop and sysctl values but not revelant and most of them were already in the "tweakaio" init script...

:(
[LG Optimus 2x] Zorkman:
Hi Vadonka,

Thanks for your great work, I have two questions though:

I want to know if my device goes into deep sleep, and how long etc. I've tried setCPU and CPU Spy, bot none of them is able to list the amount of times the CPU spent in a certain state, this would be great if you could guide me in the right direction or incorporate that in the future development of your kernel.

I can't find where I can choose the governor? Could you point me in the right direction?

It seems you've already heard that the wifi changes aren't that great, but I'll post my experience here anyway, might be helpfull:

After letting the phone sleep I'm not able to connect to a router, I needed to disable and re-enable wifi and then it would normally work.

After letting the phone sleep, going into wifi settings and letting it rescan, it would show me the routers from my last location (e.g. home) and doesn't show anything of the new location (e.g. at work), disabling and enabling wifi didn't fix this, going into airplane mode and back did most of the times, but had to reboot twice

the phone is blazing fast, but I must admit that battery life is horrible (compared to my previous android phone and my android tablet), I've got matching BB and RIL and maybe I'm doing something wrong. I'll do a battery test with antutu
[LG Optimus 2x] sander-m:
Thanks for new feb06 kernel, im now testing it ;) touch leds are fixed ;)
[LG Optimus 2x] upetro:
Hy there. I have a problem. Whenever i install this kernel on temaseks KAND build 204-55 or 204-54, android market starts to force close on me. And there is nothing i can do to stop it. I can delete the cahes from android market, then it works, as long as i dont try to download anything from it, then it force closes again.

Anyone have the same problem? What could it be?
[LG Optimus 2x] mrmaffen:
had 2 bsods within the first hour of testing your newest 6th feb kernel (32mb) :(. ill try to set minimum cpufreq 456mhz and see if this helps. greets
[LG Optimus 2x] vadonka:
456mhz is not existed in the latest, im set back the 216, 389, 503, 800, 1015, 1100, 1216, 1408 steps what i used before. its seems this is the best compromise.
[LG Optimus 2x] upetro:
hy vadonka, any ideas why i have problems with android market force closing with your kernel?
[LG Optimus 2x] silentmelodies:
I'm also liking these steps better, been running alright so far.

Btw you forgot to update the voltages in the OP :p
[LG Optimus 2x] orrebo:
I have had no problems so far.

I have not over or underclocked the cpu.

Haven't had any reason for that yet.

Thanks for a great kernel.
[LG Optimus 2x] vadonka:
thx for the notice, im updated the OP :)
[LG Optimus 2x] vadonka:
im adjusted the voltages too, it seems the 1100 mhz using a bit to low voltage so im set higher a bit, and some other adjustment.

of course undervolt is always can be possible carefully but not necessary

im adjusted the second core management too, the second core activated at 800mhz but the delay is much smaller.

it seems the overclocked avp freq also causing battery drain so im lowered to a bit, and the gpu speed is also a bit high so im lowered that too.

however the sdram freq can be a more higher and this compensate the lowered avp.

i still try to find the balance between the battery life and the performance :)
[LG Optimus 2x] Zorkman:
have you tried removing all the data from the market and uninstalling updates?

you could also try flashing the gapps again
[LG Optimus 2x] pastime1971:
@ vadonka,

in your (latest) install script,

(1) add ro.setupwizard.mode = DISABLED caused some panic for some people not being able to set up the initial google account. (maybe it needs to be warned in the first post ?)

(2) does add ro.lge.proximity.delay = 25 do anything ? i can't find its handling anywhere in cm source nor in the proprietary libs.
[LG Optimus 2x] umirza85:
My phone keeps going into airplane mode when i switch 2g/3g. When i finally manage to get it out of airplane mode all my apn's are deleted and i need to reboot to fix it. This has been ongoing on the last few kernal releases. Also using temasek's kang (always the latest)
[LG Optimus 2x] vadonka:
(1) it just disable the stock setup wizard, the google account wizard is opening anyway, this build prop property doesn't affect the google wizard app. if the stock rom setup wizard is not deleted its interfered with the google setup wizard, this will force disable the rom setup wizard only: basicly only the language settings and the keyboard tutorial in here. the second is useless, the first it not really needed.

(2) i dont know its doing something or not, it has already been in the build prop tweaks when i start to this kernel project :) if its not working then dont do anything wrong, it just plus one row more in the build.prop :)
[LG Optimus 2x] vadonka:
since only a few people have this isse and i cant reproduce this so i really need some logcat or anything what is help me to find the problem.

im not modifyed anything what is causing this, so without any log file i cant do anything more.
[LG Optimus 2x] umirza85:
How am I able to see logcat? or turn it on to start recording.
[LG Optimus 2x] pastime1971:
try alogcat app from market

edit: logcat is already on on your phone. you can access it by adb logcat. alogcat app saves them automatically.
[LG Optimus 2x] umirza85:
When i use the terminal i get adb permission denied. tried with sudo adb logcat command also - same thing.

Torrent clients somehow crash my phone. Tried 3 of them all do the same, first the phone freezes than reboots. I use the latest kernel 0 ramhack. I'm trying to download to external card, if it means something. Maybe its something with CPU?

vadonka, your latest kernel is for me the first etana kernel that works perfect and stable for me. in com ination with the latest kang from Temasek. i tried every combination temasek 50 and the latest before etana. that was the last stable until now. i happy again.
[LG Optimus 2x] B4Me:
Am I the only one, who have seen a different in mA used since the change to "ETaNa" ?

Before it became ETaNa I had a mA usage of 24mA in average, and now its 35mA in avg

I use Battery Monitor Widget, to get my data, and I've logged the battery data for the past many days, first with Jan31 kernel, and later Feb04

the 04 kernel is better than 31, but still higher than the kernel just before it became codenam ETaNa
[LG Optimus 2x] HerrKuk:
I also have that problem.

My phone always freezes with maximum OC and heavy cpu load

Vote with 5 stars for vadonka's hard work!
[LG Optimus 2x] Trystan34:
Is there a huge improvement between 32mb that 64mb?
[LG Optimus 2x] reginickneo:
The higher requirements the games have the higher RAM needed for the gpu.

GTA is able to have txt bugs with these versions (64mb ram hack or higher) but it might be usable with 64mb hack.

Or you can use chainfire 3D to reduce quality.
[LG Optimus 2x] Trystan34:
Thanks :) I think I will stay with 32mb shared :)
[LG Optimus 2x] mrmaffen:
i have set min cpufreq to 389 and it seems to have solved the bsods issues. though ive noticed quite high battery drain with normal day usage. over night it drained 20% in 8 hours. im already using toggle 2g to workaround the high 3g battery drainage. wifi is set to "when screen turns off".

when looking into my systempanel history stats, ive noticed that the cpu usage seems to peak at 10% while in sleepmode, averaging at about 3%. perhaps thats the cause for my issue? top cpu-using apps are suspend(internal system service) (9,7%) and mediaserver(internal system service) (0,6%)

also there is quite a bit of a wakeuplag when waking the device (about 1 to 2 sec sometimes)

thanks for your work vadonka :) !
[LG Optimus 2x] thewoZa:
Thanks for this kernel - along with Owains tweak pack for MIUI it makes the ROM almost perfect!

Hi, I've a problem with wifi. Phone connects to the router ok, but It hasn't internet connection (it happens with all routers). After a minute it works and It gets internet. I don't know if it's a problem related with the kernel or with the temasek kang.

Do you use the version from 4 februari? If you are using it then you should update it to the latest because that version had some problems with wi-fi.

[LG Optimus 2x] 4lph4:
Today I had a complete loss of signal with the phone unable to recover. The icons on the status bar were greyed.

I had to go into airplane mode and then back to have connection working again.

This is the log of the radio http://pastebin.com/bstK2T05

And this is the log http://pastebin.com/TB9Pwp7P

It seems to me there's a problem in the RIL.

I'm not an expert just guessing. I'm on bb725 and ril 725 v10d.

I hope it's useful to someone to understand better what happens there :)
[LG Optimus 2x] mat369:
In opposition of Thief777, I have a huge drain of battery with this kernel..

I lost more than 80% in just 11h, with a pretty light use.

The screen capture shows that i lost a big part of my battery when my screen was off.. And I think that was the led notifications, because I received an SMS when my battery starts to decrease and this decreasing stops when I read it; and because Battery monitor widget says that the activity "suspend" eat 30% of my battery, and the activity "star_ledpulse" eat 12%. Is it normal?

I OC at 1015 MHz with scaling powersave.

Thanks :)
[LG Optimus 2x] owain94:
Turn led notifications off?
[LG Optimus 2x] mat369:
I was thinking that there were a problem with leds which were fixed by de feb06 version. I already turn off leds, but if it's a real problem, I'm just trying to "unveiled" it so that it can be corrected.

Sorry if it was stupid, thanks anyway :)
[LG Optimus 2x] mrmaffen:
have the same problem like you. im losing ~3-5% per hour without using the device at all. suspend is also using 30% of battery on my device. i dont think my problem is related to led notifications though. the battery drain also happens when i have no led notification at all. will try disabling it and see if that resolved anything

hopefully we'll find a fix for this soon :)

[LG Optimus 2x] _Vegas:
:Dcool~

[LG Optimus 2x] withoutwings:
I think many people here don't understand what is possible to solve with a kernel and what isn't. Such as:

Radio crashes / loss of signal is an issue with the radio or RIL or possibly even parts of the ROM itself. The kernel has nothing to do with it.

Battery drain is lowest on wifi, then 2G, then 3G - the latter being horribly bad. Again, LG's radio code is to blame for 2G and 3G drain being the way it is. Also which network you are on and where you travel to on a particular day plays a big part and may see 40% difference day-to-day in battery life.

Don't take poor battery life in the first cycle after flashing the kernel to be an indication of worse performance. It can take 3-4 charging cycles for the phone to "settle", which tends to see some improvement.

SOD/BSOD do happen at the kernel level but are often combined with hardware variances. And hardware variances can include temperature etc and vary day-to-day; so while you may flash a new kernel version and get a BSOD when you haven't had one for a while it does not always mean that the new kernel version is necessarily worse than the last. It could be (and often is) random/bad luck. However vadonka does seem to be proactively tweaking things so that they become more unlikely to happen for people with fussy hardware.

star_led_pulse has nothing to do with the kernel. It is a CM hack to light up the buttons for notifications that quite frankly could have been implemented in a much less battery-raping way. Despite finding flashing notifications useful I have turned it off as I prefer not to run out of battery because I didn't notice a notification go off while in my pocket for a few hours.

The screen uses a lot of battery but does not show in battery stats because LG's/CM's battery stats recorder is still very crap in areas. So if you have used the phone at all during the day the % drain from the screen being on is actually much higher than it shows.

Unless you are on wifi permenently (or maybe 2G and don't use it at all) don't expect more than a day out of this device. Some battery performance improvements may be possible via the kernel but it isn't magic.

I'd just like to add that I find this kernel to be rock solid and I haven't had a single problem with it. Now I accept that I may be lucky with the hardware I have (I think I can undervolt more than most for example) but I used to get BSODs in LG's original kernel + CM kernels all the time (although I haven't tried the latest CM ones).

Radio-wise, I'm on the 823 one and I have a "Made in Korea" device. This radio is perfect for me while I've had problems of loss of signal or crashes with many other ones (haven't tried 824 so I can't comment on that) It doesn't seem to matter which RIL I use as I'm still on the default 0218_V10b this time but I've also had success with the 0725_v10d RIL in the past. They

do not

have to match, despite popular opinion! But you do need a v10x RIL with CM or MIUI and not a v20x one.

Thanks vadonka for your hard work and the fastest, most stable kernels I've ever seen on this device - much appreciated!!
[LG Optimus 2x] scrm3r:
Can anyone summarize tools and methods to test a ROM or Kernel and maybe provide the developer with a better technical details of the problem so that he can easily understand the problem, and maybe some user can rectify some trivial problem like RIL and others.
[LG Optimus 2x] Barnabe619:
Hello !

Nice work and the new updates on github seem nice :)

I have a little question: Would it be possible to lower GPU and ram frequencies while the phone is not in utilization (screen off or extreme underclock) ?

I think this could save our phones some precious mW :p

Edit : as I understand it, these features (ram and Gpu underclock) are available in spica's thread (http://xdaforums.com/showthread.php?t=1478581)
[LG Optimus 2x] plakers:
Great!!! have enough to force 2G to get some reasonale batterylife, even with U/V and profiles that locks the lower frequencies...

What kind of otpimization did you do? build.prop? sysctl? core kernel/hw modules?

I'll get my baseband back on 725 (may be 823) and waiting for this latest update. In the mean time, I've done some build.prop modifications, and installed Toggle2G to find a compromise.

For information : uptime ~32h on 2g, and 8/10h in 3g

Just installed the kernel and lauched SetCPU to check what is happening and it shows constant switching from 216 Mhz to 600 Mhz - is it normal?

hit the menu button

-Device Selection/Autodetect Speeds

if you see that the speed is jump to 241/600 then back to 216, its normal. if the phone screen is on, the cpu speed often higher than 216mhz, the setcpu polling interval is not too god, so its normal what you see.
